My understanding was that chats simply had too easy to guess names. Would this be solved by generating chat names through a cryptographic hash algorithm? I have google docs that are edible by anyone with the link and I’m kinda assuming that the link is as hard to guess as logging in with a password. Am I completely off and in dire need of reevaluating my personal web security?
